The R310E offers best-of-class performance and features, including
IP/UDP/TCP checksum and large send offload, rate control and QoS,
virtualization, and rule-based traffic steering and filtering.
The R310E employs Chelsio’s unique third-generation Terminator 3
ASIC, a high-performance, programmable protocol processor.
Terminator 3 processes all connections in a single datapath to deliver
line-rate 10Gbps performance with one connection, up to thousands
of connections. In contrast, competitive multi-RISC offload engines,
which rely on having enough connections to distribute their process-
ing among parallel processors to achieve full performance, are ulti-
mately limited by the performance of each processor.
The R310E implements a high-capacity, low-latency, high-bandwidth
iWARP RDMA/RDDP, which adheres to the IETF standards. It can
also run existing unmodified InfiniBand RDMA applications with lower
latency and higher bandwidth.
Subjected to thousands of hours of compatibility testing, over two
years of stress testing by several OEM test suites and production
deployments in servers, storage systems and cluster computing,
Chelsio’s robust, stable protocol offload technology delivers proven
performance in a wide range of environments. The S310E is genera-
tions ahead of competing products.
Chelsio offers a full suite of protocol software and drivers for Linux and
Windows with the R310E adapter. The software supports operation in
both protocol-offload and non-offload modes.
